Abstract :
We present an alternative to fabricate ultra-small air-gap micro-cavity based Fabry-Perot interferometer (AG-MC-FPIs) for high-temperature sensing by focused ion beam (FIB) machining in tapered fiber tips (TFTs). Its size is smaller than 10μm and the sensitivity is ~20 pm/°C near the wavelength of 1550 nm.
